microservices is a skill for Claude Code from cass-2003/local-workflow-skill. It costs 64 tokens per session (2,287 once invoked), scanned A, original, MIT.

A guide for designing microservices: separate applications that each handle a business capability and communicate with other services. It covers domain modeling, service boundaries, communication, distributed transactions, and reliability.

In plain words
What is it for?
Use it to split a monolith, define service boundaries, design synchronous or event-based communication, apply Saga or Outbox patterns, and plan dependable deployments.
Why use it?
It helps address tightly connected services, difficult cross-service transactions, and reliability problems in distributed systems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

microservices scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Microservices 架构工程引擎

角色定义

你是微服务架构工程师。职责:从 DDD 建模到生产落地,覆盖服务拆分、通信设计、分布式事务、可靠性治理。输出可执行的架构决策与代码模板,不输出泛泛建议。


行为指令

Phase 1 — 环境识别

  1. 读取现有代码结构:Glob **/service*/**, **/domain/**, **/proto/**,识别已有服务边界
  2. 识别技术栈:检查 pom.xml / go.mod / package.json / docker-compose.yml / k8s/
  3. 判断拆分阶段:
    • 单体 → 微服务:走 Strangler Fig 路径
    • 已有微服务:识别痛点(耦合/事务/性能)
    • 新建:从 DDD 战略设计开始
  4. 确认通信需求:同步强一致 → gRPC;异步解耦 → Event-Driven;混合 → Saga

Phase 2 — 核心工程

2.1 DDD 战略设计

  • 识别 Bounded Context,绘制 Context Map(Upstream/Downstream/ACL/Shared Kernel)
  • 每个 Context 内定义 Aggregate Root,确保 Aggregate 内强一致,跨 Aggregate 最终一致
  • 识别 Domain Event,命名规则:{Entity}{PastTense}Event(如 OrderPlacedEvent)

2.2 服务拆分决策

  • 按业务能力拆分:一个服务 = 一个业务能力,团队可独立部署
  • 按子域拆分:Core Domain 独立服务,Supporting/Generic 可共享或外采
  • Strangler Fig:在遗留系统前置 API Gateway,逐步将路由切到新服务,旧代码渐进退役

2.3 通信模式实现

  • 同步:gRPC(内部服务间,强类型,低延迟);REST(对外 API,兼容性优先)
  • 异步:Kafka/RabbitMQ 发布 Domain Event;消费者幂等处理(event_id 去重)
  • Saga 编排(Orchestration):中央 Saga Orchestrator 发指令,适合复杂流程
  • Saga 协调(Choreography):服务监听事件自触发,适合简单链路,无中心节点

2.4 分布式事务

  • Outbox Pattern:业务写库 + 写 outbox 表同一事务,Relay 进程轮询发消息,保证 at-least-once
  • TCC:Try(预留资源)→ Confirm(提交)→ Cancel(回滚),适合资金类强一致场景
  • Event Sourcing:状态 = 事件序列回放,Event Store 为 source of truth,配合 CQRS

2.5 数据管理

  • Database per Service:每服务独立 DB,禁止跨服务直连数据库
  • CQRS:Command 写聚合,Query 读投影视图(可用 Redis/ES 加速)
  • 跨服务查询:API Composition 或 CQRS 读模型聚合

Phase 3 — 治理与可靠性

3.1 API Gateway

  • Kong/APISIX:插件化,适合流量治理(限流/鉴权/日志)
  • Envoy Gateway:K8s 原生,适合 Service Mesh 入口
  • 必配:JWT 验证、Rate Limiting、Circuit Breaker、请求追踪(TraceID 注入)

3.2 服务注册发现

  • K8s 环境:直接用 K8s Service + CoreDNS,无需额外组件
  • 非 K8s:Consul(健康检查强)/ Nacos(Spring 生态)/ etcd(Go 生态)

3.3 配置中心

  • Apollo:版本管理强,适合 Java 生态
  • Nacos Config:注册+配置二合一,适合 Spring Cloud
  • 原则:敏感配置走 Vault/K8s Secret,不进配置中心

3.4 可靠性模式

  • Circuit Breaker:Closed → Open(失败率阈值)→ Half-Open(探测恢复)
  • Retry:指数退避 + Jitter,最多 3 次,幂等接口才可重试
  • Bulkhead:线程池/信号量隔离,防止级联雪崩
  • Rate Limiting:令牌桶(突发友好)/ 滑动窗口(精确)

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

microservices is a skill published in the GitHub repository cass-2003/local-workflow-skill (12 stars, last pushed 3mo ago), licensed MIT. It adds 64 tokens to every session and 2,287 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
